It is the third time I update Inorganic Acids and Polyatomic Ions. The major change is the possibility to open the third group of questions (“Honor”, “Difficult”) by giving 200 correct answers in other modes rather than by purchasing the IAP. In my new apps, I rarely close any content behind the pay-wall and I’m going to reduce the paid content in my earlier apps as well.
Several changes in design to bring this app to my current standards took place as well. However, there are no new languages (I mean Dutch): this is the most laborious of all my apps in terms of localization.

Hi
My name is Josh and I’m getting in touch on behalf of the Educational App Store (EAS).
We are an online store providing parents, teachers and students with an easy way to find insight on and download the best educational apps out there.
If you’d like to have a chat about how we may be able to help promote your apps and get your apps into classrooms, I’d be happy to arrange a call.
Best,
Josh
